The Bosnia international, who joined City from Wolfsburg in January 2011, was strongly connected with a move away from the Premier League champions in the summer but the club's football development executive indicated that any interest shown in the forward man by the Serie A holders would be a waste of their time.

"Dzeko to Juve? For us he is a key player," Vieira told Tuttojuve.com.

"Did you see that goal he scored against Real Madrid [on Tuesday]? I'm sorry for the Bianconeri fans but the extraordinary strikers do not move from Manchester."

Dzeko has enjoyed a fruitful start to the season with three goals in five appearances in all competitions, with a total of 28 goals in 68 games for City since his move from Germany.

The forward's strike against Los Blancos on Tuesday ended up being in a losing cause as the Spaniards came back to win 3-2 in the Champions League encounter.
